Monitoring D'Link DGS1248-T

[philippn]

Hi,

I'm trying to monitor one of my D'Link DGS1248-T switches.
Receiving the data via SNMP works.

As I like to monitor the bandwith of our backbone, I added some Items (e.g. Output of Port 46):


<item type="1" key="o46" value_type="3">
<description>Out 46</description>
<delay>10</delay>
<history>90</history>
<trends>365</trends>
<status>0</status>
<units>B</units>
<multiplier>1</multiplier>
<delta>2</delta>
<formula>8</formula>
<lastlogsize>0</lastlogsize>
<snmp_community>public</snmp_community>
<snmp_oid>.1.3.6.1.2.1.2.2.1.16.46</snmp_oid>
<snmp_port>161</snmp_port>
</item>


But there is something wrong because I have a current bandwith of 1.39 GBit/s, what (unfortunatelly) not possible.

I think I use a wrong multiplier..but what's the correct value?

With best regards from Germany,
Philipp

Is it consistently wrong? Try clearing the history if you've been changing the multipliers.

Thx for that tip, but it doesn't work.

Any other ideas?

Typically, a switch port from which you want to get the current bandwidth is supposed to be configured like this (configuration -> items -> targeted item )

- Type of information : numeric (float)
- Units : B
- Use multiplier : Do not use
- Store value : Delta (speed per second)

If your switch is not an obscure and non-standard SNMP device, it should work;

Btw, have tried to look at the template's switchs configuration ? it might help :)
